How to Choose the Right AI Video Workflow
Indepra now supports more than a dozen AI video workflows — text to video, image to video, multi-image, lip sync, first and last frame, and more. The hardest part is no longer generating video. It’s picking the right workflow before you spend credits. This guide breaks down each workflow, what it’s best for, and when to use it.
Why Workflow Choice Matters More Than Model Choice
Most people obsess over which model to use — Kling, Veo, Seedance or Hailuo. But in practice, the workflow you pick decides whether the output is even usable.
A text-to-video prompt will never preserve a product label. An image-to-video workflow will never invent a scene you haven’t shown it. A lip sync workflow expects audio, not a creative prompt. Choosing the wrong workflow wastes credits before the model even runs.
The 6 Main Workflow Types
| Workflow | What You Provide | Best For |
|---|---|---|
| Text to Video | Only a prompt | Cinematic scenes, mood, environments, abstract ideas |
| Image to Video | One image + prompt | Product shots, portraits, animating a photo |
| Multi-Image to Video | 2–9 images + prompt | Character consistency, storyboards, product angles |
| First & Last Frame | 2 images (start + end) + prompt | Transitions, reveals, controlled motion between states |
| Lip Sync | Image + audio | Talking characters, voiceovers, dialogue previews |
| Multi-Image + Audio | Images + audio + prompt | Music-driven sequences, narrated slideshows, social clips |
Which Workflow Should You Use?
🎬 You have an idea but no image → Text to Video
Use this when you want to describe a scene from scratch. Best for cinematic action, fantasy landscapes, sci-fi reveals, or any scene you can picture but haven’t shot. The prompt does all the work.
🖼️ You have one strong image → Image to Video
Use this for product photos, portraits, or any still you want to bring to life. The image locks the subject and composition; the prompt only describes motion. This is the safest workflow for e-commerce because the product stays recognizable.
📸 You have multiple images of the same subject → Multi-Image to Video
Use this when you need consistency across angles. A product photographed from three sides, a character from different angles, or a storyboard sequence. The model uses the references to keep identity stable.
↔️ You know how it starts and ends → First & Last Frame
Use this for controlled transitions. A product changing state, a character shifting expression, a scene morphing into another. You pin the start and end; the model fills the motion in between.
👄 You have audio and a face → Lip Sync
Use this for talking characters, voiceover previews, or dialogue scenes. The prompt matters less here — the audio and the face drive the result. Best for short clips under 10–15 seconds.
🎵 You have images and music → Multi-Image + Audio
Use this for music-driven sequences, narrated slideshows, or social clips where audio sets the pacing. The model combines your visuals with the audio track.
Common Workflow Mistakes
| Mistake | Why It Fails | Better Choice |
|---|---|---|
| Using Text to Video for a product shot | The model invents the product; label and shape drift | Image to Video |
| Using Image to Video for a scene you haven’t shown | The model only animates what’s visible | Text to Video |
| Using Lip Sync without audio | The workflow expects a voice track | Image to Video or Text to Video |
| Using First & Last Frame with unrelated images | The transition looks broken or morphing | Use frames with shared subject/composition |
| Using Multi-Image with conflicting styles | The model averages the styles and loses identity | Keep reference images consistent |
How to Test Workflows Without Wasting Credits
- Start with the shortest duration. Test at 5 seconds before committing to 15.
- Use the cheapest model for tests. Seedance or Hailuo are faster and cheaper than Veo Quality for exploration.
- Write one clear motion per test. Don’t test five ideas in one generation.
- Compare the same prompt across workflows. Text to Video vs Image to Video with the same idea shows you the difference fast.
FAQ
Can I use the same prompt across different workflows?
You can, but the result will differ. Text to Video interprets the full prompt; Image to Video only uses the motion parts. Adjust the prompt to the workflow.
Which workflow is best for e-commerce?
Image to Video for product shots. Multi-Image to Video if you have multiple angles. First & Last Frame for state changes (before/after, color variants).
Which workflow is best for social media?
Text to Video for cinematic hooks. Image to Video for product clips. Lip Sync for talking characters. Multi-Image + Audio for music-driven content.
Do all workflows support 9:16 vertical?
Most do. Check the workflow settings before generating — some legacy workflows may be 16:9 only.
Can I switch workflows mid-project?
Yes. Many creators use Text to Video for the hook, Image to Video for product shots, and Lip Sync for dialogue — all on one credit balance.
